Bug Description

I'm not quite sure where to look for logs/details, so if someone could enlighten me i will provide more data. Stream2ip does not properly stream audio to my AirTunes enabled Denon AVR-1912 AV receiver, while airfoil on windows as well as itunes/ipods/iphones work properly.

For Air Play:

- make sure the IP and port is correct on both, stream2ip and the receiver
- open this port for streaming
- RAOP1 may not be implemented on the Denon (we are unable to test this). Until RAOP2 is available from pulseaudio we may not be able to stream to a RAOP2 only device (see also bug #790827).
- streams may have a delay of several seconds.

Q: are you able to stream by using the pulseaudio method implemented with paparefs?
Q: run `stream2ip -v' in a terminal to view errors.

Much better alternative:

- choose "Internet Radio" mode "live" from stream2ip for a much better performance
- after setting up Icecast2 you may need to edit ~/.stream2ip/darkice-s2ip.cfg to change the stream from .m3u to .mp3:

    mountPoint = stream2ip.mp3 # mount point on the IceCast2 server

- register your receiver, and stream2ip at using the follwing "radio station":

    http://<your local ip>:8000/stream2ip.mp3 (use the **local** IP of your Icecast server, e.g. 192.168.178.xx.xx)

Let us know if we can be of further help. Stream2ip is definitely designed to work with your fine receiver in one way or the other.

Pulseaudio recognizes the receiver in its listing of audio devices, but when it is selected as the output device, it does not work at all.

Thank you for the output of stream2ip.

We can see that your settings say your receiver listens to port 8080 wheras stream2ip still uses the fallback port 5000 (which is the default for an AirTunes device). Obviously there is an issue with recognizing the port given in options.

This is currently under investigation. So far we are unable to reproduce this behaviour.

Are you able to receive a RAOP stream when you set the Denon receiver to listen to port 5000?

The receiver does listen on port 5000, im not sure why it tried to connect on 8080

chuck@sepang:~$ sudo nmap -O -v -A -p 5000

When setting it to port 5000, it does not work at all either. attached to this message is what it looks like when it is connected, but the receiver does not play any music at all

Thank you for the quick response. I expect stream2ip to look like that as soon as you can ping you receiver.

In fact stream2ip will always assume you want to connect to a RAOP device on any IP you give it. Due to a lack of feedback from the (closed source) RAOP protocol we can not provide any workaround for this less happy behaviour. We just have to rely on a RAOP device on that IP, sorry for that.

Did you try to set up streaming via Avahi as offered by pulseaudio paprefs?

If that fails despite your receiver is available and is selected in the sound settings it is very likely that the receiver is not compatible with the RAOP streams offered by pulseaudio-module-raop used by stream2ip.

I then recommend you try streaming with the Icecast streaming method that gives you the following advantages over AirPlay

- customizable Bitrates
- much shorter delay (1-2s only)
- can be listened by any Internet Radio capable device on the network
- displays limited tags (Artist - Song) on the stream description when using an MPRIS capable media player
- open stream format compatible with Shoutcast
- local sound is untouched
